STORY: Netflix CEO Calls 'House of Cards' Down Payment on Original Content

Hargreaves predicts that Netflix will grow its base of U.S. streaming subscribers to 36 million by the end of 2015, whereas it had 27.2 million at the end of last year. He is also bullish on Netflix's original programming.

"Netflix's huge database of subscriber viewing habits should allow it to invest in original content where it will be most effective, while purchasing third-party content across an array of genres that can attract an extremely large audience," Hargreaves wrote.
